@@ -8,7 +8,8 @@ A number of changes were made to the configuration options passed to the plugin
 
  * `xScaleID` option default has been changed, now set to `undefined`. If the option is missing, the plugin will try to use the first scale of the chart, configured as `'x'` axis. If more than one scale has been defined in the chart as `'x'` axis, the option is mandatory to select the right scale.
  * `yScaleID` option default has been changed, now set to `undefined`. If the option is missing, the plugin will try to use the first scale of the chart, configured as `'y'` axis. If more than one scale has been defined in the chart as `'y'` axis, the option is mandatory to select the right scale.
-* When [stacked scales](https://www.chartjs.org/docs/latest/axes/cartesian/#common-options-to-all-cartesian-axes) are used, instead of the whole chart area, the designated scale area is used as fallback for `xMin`, `xMax`, `yMin`, `yMax`, `xValue` or `yValue` options.

+ * `cornerRadius` option was replaced by `borderRadius` in the box annotation configuration and in the label configuration of line annotation to align with Chart.js options.
